ram sinks

[Spawn-Inc]

do ramsinks work good or is it just a waste of money? and how does one go about attaching one to the gpu ram? i built my own (cut up a old heat sink) and just used arctic silver 5 to hold them on the tops only. will that make any real difference? i added them cause i think its over heating and freezing my game.

here are some pictures, there blurry but you can see that i added the blue heat sinks.

They make "thermal epoxy" just for this. It is a 2 part mixture just like epoxy, but heavy in thermal conductive material. I have had to repair MANY SUN and SGI boards since that is what they use, no clips.

The official name of the one I have is; Arctic Alumina Thermal Adhesive. Made by arctic silver;

well mostly what i want to know is what i did, just using AS5 to hold it on, transfer heat as good or better than it not being there?

BUMP!!!!

welll if it wasnt there A there would be gaps in between hs and card, B arent the back or HS's electronically conductive?

[Airbozo]

Yes, it is better than not being there. One thing about the AS5, is that it will not hold those sinks on for long. Eventually they will fall off and maybe short something... Of course I was using a much larger heat sink when I made that discovery...

you know there are spots on the card you can drill another hole into? as long as you dont hit any of the ib cabling you could even make a braket for it all.

Please don't do anything based on my advice and someone quickly correct me if I'm wrong because I've never "modified" my video card.

Looks like you placed the RAM sinks on the back of the video card. Which would mean that you aren't actually putting the heatsinks on the actual RAM, just on the back where all the soldering is. The RAM chips should be on the other side of the card, which is the same side as the fan/heatsink for your GPU core.

...some cards do have the ram chips on the back as well as the front...

His chips are visable under the sinks

yes mine has 8 ram chips and 4 are on top and 4 directly under the top 4.


here are clear pictures

Good idea. Just use thermal epoxy or thermally conductive tape to hold the heatsinks in place.
